My 3ds won’t turn on, homebrew error shows up

Basically, I got a N2DS today and forgot to transfer my N3ds files to it. No big deal, it’s whatever. I tried linking my Nintendo ID to the 2ds, but it said it was already linked to a 3ds. I tried system transferring my 3ds to 2ds, but, it told me to system update. Alright, I do a system update but the moment it finished, Homebrew popped up and it says “An error has occurred: failed to apply 1 FIRM patch(es). Press any button to shutdown.” Everytime I push down a button, the same message shows up and it stays on the black screen. I’m not tech savvy at all and all my guy friends did all the modding for me.
